Abstract (en)

Systems and methods for controlling the sensing of an occupant in a seating area are provided. The occupant is characterized as one of an adult, child or other category. One characterization change parameter, such as a hysteresis time period or thresholds for characterization, is applied for a first time period. After that time period, the characterization change parameter is changed. For example, if the characterization stays the same for ten seconds, the hysteresis is changed from five to ten seconds. As another example, if the characterization stays the same for one minute, the thresholds associated with that characterization are broadened to decrease the likelihood of a change in characterization. In some systems and methods, a confidence parameter or probability associated with the characterization is used to control the changes of the characterization change parameter. In some systems and methods, the characterization change parameter is reset in response to one of (a) a no occupant characterization or (b) characterizing the occupant as a different one of the at least two categories consecutively for a current hysteresis time period. <IMAGE>
